I'll be at the Bay Area Maker Faire on May 18 & 19. My application has been accepted and my flight has been confirmed.
And I just launched a new KickStarter campaign: The Xminilab Portable
The XScopes
The XScopes are a combination of three electronic instruments: a mixed signal oscilloscope, an arbitrary waveform generator and a protocol sniffer. The XScopes can also be used as development boards for the AVR XMEGA microcontroller. The Xprotolab and Xminilab can be plugged directly on a breadboard.
Main Features:
- Mixed Signal Oscilloscope: Simultaneous sampling of 2 analog and 8 digital signals.
- Arbitrary Waveform Generator with advanced sweep options on all the wave parameters.
- Protocol Sniffer: SPI, I2C, UART
- Advanced Triggering System: Normal / Single / Auto / Free, with many trigger modes; adjustable trigger level, and ability to view signals prior to the trigger.
- Meter Mode: VDC, VPP and Frequency readout.
- XY Mode: For plotting Lissajous figures, V/I curves or checking the phase difference between two waveforms.
- Spectrum Analyzer with different windowing options and selectable vertical log and IQ visualization.
- Channel Math: add, multiply, invert, and average.
- Horizontal and Vertical Cursors with automatic waveform measurements, and waveform references.
